MACHINE FOR MAKING LACE TRIMMINGS.

SPECIFICATION forming part of Letters Patent No. 781,387, dated January31, 1905.

Application filed November '7, 1904. Serial No. 231,660.

To all whom it may concern.-

Be itknown that 1, MAX N. AARON, a citizen of the United States,residing at Philadelphia, county of Philadelphia, and State ofPennsylvania, have invented a new and useful Improvement in Machines forMaking Lace Trimmings, of which the following is a full,

clear, and exact description, reference being had to the accompanyingdrawings, which form a part of this specification.

My invention relates to machines for making lace trimmings, and is animprovement on or addition to the machine set forth and claimed in anapplication filed by me July 23, 1904, Serial No. 217,774. This priorapplication sets forth a machine which is adapted to inserta ribbonautomatical-lyin the ribbonspace of the fabric in the process ofknitting the fabric. acter which the machine of said application isdesigned to make consists of a heading composed (usually) of threelongitudinal threads crossed by a number of transversethreads and aribbon-space formed between one of these longitudinal threads andanother longitudinal thread connected together by transversepillar-bars. The ribbon or braid is inserted in this space by passing itlongitudinally in front of and back of alternate bars. While the machineof my prior application is operative to make a fabric of this kind and 8insert the ribbon automatically in the process of knitting, no means aredisclosed the'reinto form loops in the ribbon at determinate distancesalong the trimming. It is frequently desirable to sell thelace trimmingwith the ribbon so looped. To do this is the object-of my presentinvention, which consists in additions to or modifications of themachine of my the machine with some of the parts removed. Fig. 3 is asection on the line 3 3 of Fig. 1. Fig. 4 is an enlarged view ofaportion of the mechanism shown in Fig. 3 with the parts in a differentposition. Fig. 5 is a detail view A typical trimming of the char-'positively toward the point of in elevation of the support for the feedmechanism. Fig. 6 is a section on the line 6 6 of Fig. 2. 'Fig. 7 is aperspective view of the looping-finger. Fig. 8 is a front view of afabric made on a machine embodying my invention, and Fig. 9 is a sectionon the line 9 9 of Fig. 8.

I shall not describe with particularity the construction or operation ofthe machine in its entirety, as the said machine is in its main featuresa well-known typeof what is known in the art as a rib-lace machine, andthe means enabling the ribbon to be automatically inserted in theprocess ofknitting the fabric are fully ,set forth in my priorapplication. I shall, however, refer to its main features and shall fora better understanding of the present invention particularly describethe ma chine of my prior application, as well as the novel features thatdistinguish my present invention therefrom. It will, however, beunderstood that my invention is not limited in its application to theparticular type of machineshown, which is merely a type of machine towhich 1 have already applied my in- 'vention' and in connection withwhich I prefer cl. The ribbon-space is formed by the longitudinal threadg and the threads 6 and f, the latter each being twisted along thethread 9 and also extending transversely back and forth between threadsg and 0 and looped on the latter, the threads 0 and f thereby formingdouble transverse pillar-bars alternating with each other and spanningthe space between threads 9 and c. The inner thread 0 of the heading mayalso be said to constitute the inner thread of the ribbon-space, being,in effect, the dividing-thread between the ribbon-space and heading. Theribbon z is in.

serted in this space, being held in place by extending in front of eachbar formed by thread 0 and back of each bar formed by thread f, or, inother words. extending in front of and back of alternate bars. Atdetermined distances along the trimming the ribbon is drawn outwardlybeyond the plane of the fabric to form loops y, these loops being shownin Fig. 9 as being formed between alternate crossbars, although they maybe formed at any suitable distances apart. After the trimming is placedupon a garment, such as ladies underwear, and the garment put on theribbon is drawn more or less tightly through the trimming for thepurpose of adjusting the garment to the wearer, and the excess length ofribbon so produced may be formed by the wearer into an ornamental bow ortie. The machine embodying my invention is adapted to insert the ribbonand form the loops therein in the process of knitting the trimming.

The fabric referred to is only one of numerous fabrics having interwoventherein a ribbon or braid, and such fabric is to be considered merely asillustrative and as an aid to an understanding of my invention and notas representing the only style of fabric to the manufacture of which myinvention is applicable, my invention, in fact, being applicable to themanufacture of any lace or kitted fabric containing a ribbon or braid.In the production of this fabric a series of guide-bars are employed,each of which, except one, carries a series of thread-guides and one ofwhich carries a series of ribbon-guides, all of the bars being adaptedto oscillate back and forth and some of the bars being adapted to begiven a longitudinal movement and all of the guides cooperating with theusual vertically-reciprocating needle-bars carrying the needles.

h is the rear guide-bar, to which are fastened the plates 1', carryingthe guides j, said guides holding in position the longitudinal threads 0of the heading. These bars are substantially stationary so far aslongitudinal movement is concerned. It is the next adjoining guide-bar,to which are fastened plates Z, carrying the guides m, said guidesgoverning the position of the transverse thread 01. These bars areadapted to have a regular longitudinal reciprocating movement, so as todirect the thread d back and forth between the outer and inner threads 000f the heading to form the transverse bars thereof. n is the nextadjoining guide-bar, to which are fastened the plates 0, carrying theguides 12, said guides governing the position of the thread a and beinggiven an intermittent longitudinal reciprocating movement to formalternate cross-bars spanning the ribbon-space between the inner thread0 of the heading and the thread 9. q is the next adjoining guide-bar butone, to which are fastened the plates 1', carrying the guides 8, saidguides governing the position of the thread f and being given l anintermittent longitudinal reciprocating movement (alternating with thesimilar movement given to the guides 71) to form alternate cross-barsspanning the ribbon-space between the inner thread 0 of the heading andthe thread 7. t is the front and next adjoining guide-bar, to which arefastened the plates 11, carrying the guides '11, said guides holding inposition the outer longitudinal thread of the ribbon-space. These barsare substantially stationary so far as longitudinal movement isconcerned.

Between the guide-bars a and q is a guidebar w, said guide-bar havingsecured thereto a bracket or ribbon guide it, having a shouldered orenlarged lower end containing a wide but shallow orifice whosedimensions permit the insertion therein and passage therethrough of theribbon .2, the specific construction of this ribbon-guide being morefully set forth in my prior application. The guide-bar M has nolongitudinal movement.

10 is the usual needle-bar, to which are socured the plates 11, carryingthe needles 12. The particular arrangement of the needles with relationto each other and to the guides need not be herein particularlydescribed, as the same is fully set forth in my prior application and anunderstanding thereof is not necessary to an understanding of my presentinvention. It is suflicient to say that a set of needles is provided tocooperate with the set of guides described and that a vacant space isprovided between needles, which space is located under the ribbon-guidew and is adapted to allow the passage therethrough of the ribbon as itis fed forward in the operation of the machine in the manner hereinafterde scribed.

It will be understood that each guide-imicontains a series of guidesextending throughout its length and that the needle-bar contains acorresponding series of needles, so as to permit the simultaneous makingof a number of distinct sections of fabric. It will also be understoodthat only such guides of each guidebar are at any given time in activeuse as are necessary to guide the threads which its guide-bar isdesigned to control. It will also be understood that as the severalsections of fabric are spaced apart during manufacture a certain numberof the needles are idle. it will be understood that there are as manyactive sets of guides and as many active sets of needles as there aresections of fabric to be simultaneously produced.

21 represents brackets depending from shaft 20.

22 represents supports secured to brackets 21.

23 is a series of guide-bar holders, one for each guide-bar. saidholders being slotted at 24 to receive a bolt 25, engaging the support22, whereby the guide-bar holders are adjusta cross-head 28 is securedto the shaft 2O.

This cross-head is slotted-at 29, and in said slot are a plurality ofadjustable bolts 30.

spectively, th'e bolts 30. Secured to each le- .Ver 31 is one end of aconnecting-link 32, the other end of which is hooked into the orificedend of a bar'33, adjustably secured to one arm of a bell-crank lever 34,pivoted on a bracket on the machine-frame. The other arm of thebell-crank 34 carries a roller 36, engaging a pattern-chain 37,extending around a. pattern-wheel 38 on the shaft 39.

' The shaft 20 is oscillated by the usual means,

(not herein shown,) thereby, imparting the usual oscillatory movement tothe guide-bars.

The pattern-shaft 39 is given a step-by-step rotary movement by theusual means, (not herein shown) thereby feeding the severalpattern-chains 37 and rocking the bell-cranks 34, and consequentlygiving the appropriate longitudinal movement to the guide-bars withwhich said bell-cranks are respectively connected. Such of the hookedlevers .32 as are connected to the guide-bars to which no l'ongitudinalmovement is to be imparted may be disconnected fromthei r respectivebell-cranks, v

or thecorrespon ing bell-cranks and patternchains may be removed oromitted. -While the ribbon-guide bar to is shown supported from theshaft 20 in the same manner as the other guide-bars, it is obvious thatthe particular way in which it is supported terial. q

7 The needle-bar 10 is secured .in the usual manner to rod 40, whichextends down through guides 41, secured to the machine. I The rod 40 isgiven a Vertically-reciprocating movement by the usual means. (Notshown.)

By reference thereto the I the ribbonffeeding in front of the transversebars formed by the thread 0 and back of the transverse bars formed bythe thread f, thereby causing the ribbon to .be drawn or fed through theribbon-space alternately in front of and back of successive transversebars of the ribbon-space in the course of manufacture of the fabric.

I will now particularly describe the novel features of the machineembodying the in vention forming the subject-matter of my presentapplication. I will first refer to Fig. 4, this figure showing in detailthe mechanism which directly acts on the ribbonfor effecting the loopingoperation.

50 is a slide'on each side of the machine, said slide being adapted towork back and forth. toward and from the needle-bar. 51 is a guidewithin which the outer end of the slide moves. This guide consists of a'side member, against which the outer end of the slide fits, and an upperand lower member, respectively, partially overlying and underlying theslide. 52 is a guide-plate secured to the guide 51, said plate extendinga short distance below the lower surface of the overhanging member ofthe guide 51 and extending in portion extends somewhat above theremainder of the slide. Thus the slide'is prevented from beingdislodgedfrom its guideway, while full freedom of movement back and forth ispermitted. 53 is a slide-bar extending the width ofthe machine andsecured at its ends to the slides 50. 54is a forwardly-extendinglooping-finger (shown in detail in Fig. 7) having a s'lottedrear member55, secured to the slide-bar 53 by means of a screw 56 in the slide-bar.This looping-finger is of about the width of the ribbon 2.. It has alimited adjustment along the slide-bar 53 by means of said screw andslot, so that it may be adjusted It will be understood that there are asmany of these loopingfin'gers as there are sections of trimming be- Theslide is provided with a large number of holes in excess of the maxi- Imum number-of looping-fingers that will at any time be used, so that thelatter may be adjusted along the slide-barat any desired precise points.The slides, slide-bar, and looping-finger are' normally in the positionshown in Figs. 2 and 3namely', the forward end of the looping-finger isa short distance back of the needle-plate 42. 57 is an angle-ironsecured to the machine-frame at each side thereof, and 58 is anabutment-plate secured to the angle-irons. This abutment-plate isdirectly beneath the needle-plate 42, a slightspace being left betweenthe two plates to permit, the

ready passage between them of the loopingfingers 54. As the fabric isbeing woven it and the guide-bar q-for the thread f insures 7 9 innerend of the overhanging member of the IIK' cured to and beneath the slide50.

abutment-plate 58. Atpredetermined intervals and by mechanism to behereinafter described the slides are moved forwardly asufficientdistance to cause the looping-fingers to pass between the said plates,as shown in Fig. 4, and between the threads 0 and g of the trimming,engaging the ribbon and pulling it through to form the loop 1 as shownin Fig. 9.

It is evident that provision must be made to compel theloop to be formedby pulling the ribbon from above, as if it were pulled from belowitwould result in pulling in and destroying previously-formed loops. Toprevent, therefore, any upward movement ofthe ribbon during theoperation of the loopingfingers, I have provided the following mechanismfor directly acting upon the ribbon for the purpose of holding inposition during the formation of a loop the loops previously formed: 66is a clamping-bar secured at each end to a rod 61,which extends throughorifices in the front and rear legs of a bracket 62, se-

63 is a pin or stop on the rod 61. 6 1 is a spring confined between thepin 63 and the rear leg of the bracket 62. The clamping-bar isnormallyin the position shown in Fig. 3 namely, the forward end of theclampingbar is a short distance back of the abutment-plate 58 andpreferably slightly in front of the front end of the slide-bar 53. Asthe slide-bar 53 is moved-forwardly. as before described, theclamping-bar 66 is also moved forwardly until it abuts against thetrimming-back of the abutment-plate 58. Thereafter during the passage ofthe looping-fingers between the plates 58 and 42 the rear leg of thebracket 62 compresses the spring 64, causing the lat ter to press theclamping-bar forwardly with a strength dependent on the tension of thespring, confining the trimming tightly between the clamping-bar and theabutmentplate, and consequently holding the ribbon from movement.

From the foregoing description it will be apparent that the length ofribbon required to form a loop must necessarily be formed by drawing theribbon downward from its source of supply and that there is no danger ofdrawing in and destroying a loop that is once formed. It is alsoadvisable, while the looping-lingers are inoperative, to prevent thetension on the trimming exerted by the guidebars in their oscillationback and forth from drawing up the ribbon and partially or whollydrawing in the previously-formed loops. To this end I provide a holdingdevice or friction roller 661, extending across the machine-back of theupper portion of the needle-plate 42, said friction-roller being hung onlevers 67, pivoted on brackets 68, secured to the upper end of theneedle-plate and nor-- mally by its weight pressing against thetrimming, as it is formed, with sufiicient force to prevent the ribbonfrom being pulled upwardly. The pressure of this friction-roller,however, need not be sullicient to prevent the ribbon being fed forwardwith the trimming, as the latter is formed by means of the usual take-uproll. It is necessary, however, that this roller should be retractedduring the operation of the looping-lingers, as otherwise the action ofthe latter in pulling down the ribbon would be interfered with by thepressure of the roller. To effect this purpose, I provide the followingmechanism: 70 is a shaft extending across the loom and turning at eachend in a bearing formed in a bracket 71, which also supports the guide51 previously described and which is itself supported on a standard '72,secured to the machine-frame. The shaft 70 is intern'iittently operatedby mechanism hereinafter described. Secured to the shaft at each side ofthe machine is a bell-crank lever 73, one arm of which is connectedthrough alink H with the slide 50. The othe arm of each bell-crankextends immediately under the axle of the corresponding friction-roller661. As the shaft 70 is turned on its axis, so as to move thebell-cranks from the position shown in Figs. 2 and 3 to that shown inFig. 1-, the slides 50 are moved forwardly to operate thelooping-lingers 5 1 and clamping-bar 66, as before described, and at thesame time the roller 661 is lifted away from its operative position intothe position shown in Fig. 1, thereby pern'iitting the ribbon to freelyfeed downwardly under the pulling action of the looping-lingers. As theshaft 70 is returned to its normal po sition the slides 50 areretracted, witlulrawing the looping-lingers 5st and clamping-bar 66, andthe roller 661 is permitted to again drop into operative position.

In place of employing the friction-roller 661 to prevent the pulling upof the ribbon in the trimming previously formed and looped I may utilizethe clamping-bar 66 for the purpose. It will be understood'that in allmachines for making lace trinnning a pawl-andratchet mechanism (notshown) is employed to operate a take-up roll, (not shown,) whereby thetrinnning after each course of knitting is fed forwardly. During theoperation of the take-u p roll the clamp 66 must of course be in itsretracted position, as shown in Figs. 2 and 3, so as not to interferewith the intermittent feeding forward of the trimming. Moreover, thereis no necessity during the operation of the take-up roll for providingany special means to prevent the ribbon be ing pulled up by theguide-bars, as the stronger downward pull exerted by the take-up rolloffectually prevents this. The neeesslty for providing this specialmeans exists, therefore, only while the take-up roll is inactive. Itwill be understood, therefore, that if the clamping-bar is movedforwardly, so as to press the trimming against the abutmentplate 58during the time that the take-up roll is inactive, the ribbon will atall times beheld from upward movement. I therefore cause I the slide 50to move forwardly after each pulled upwardly or the friction-roller 661may be employed, and the clamping-bar may be thrown into action onlyduring the operav tion of the looping-fingers. or the clampingbar may bethrown into action after each operation of the take-up roll and thefrictionroller 661 omitted. I

I shall now describe the mechanism for intermittently turning the shaft70. I have hereinbefore stated that pattern-chains 37, extending arounda pattern-Wheel 38 on the shaft 39, engage rollers 36 on bell cranklevers 34 for the purpose of giving the appropriate longitudinalmovement to the guidebars with which said bell-cranks are respectivelyconnected. I select one of the bellcrank levers 34 not connected with aguidebar for the purpose of actuating the shaft 70. To the end of theroller-carrying armof such bell-crank is secured an arm 76.

79 is a shaft turning in bearings in the machine-frame.

78 is a lever secured to shaft 79.

77 is a connecting-rod between the outer end of lever 78 and the end ofarm 76.

a lug 83 passes under and elevates the end of said bell-crank, the chainof mechanism just described turns the shaft to the extent necessary tomove into action the'loopingfingers and the clamping-bar and withdrawfrom operative position the friction-roller. When the lug 83 passes fromunder said bellcrank, the latter drops, restoring shaft 70 to its normalposition, Withdrawing the loopingfingers and clamping-bar, andpermitting the friction-roller to again drop into operative position.When it is desired to bring theclamping-bar into operation after eachaction of the take-up roll, as well as during the operation of thelooping-fingers, 1 provide the patternchain with low lugs 107, .as wellas high lugs 83. When a low lug is moved under said bell.- crank, thechain ofmechanism leading to the slide 50 is operated and the slide ismoved forward sufficie'ntly far to move the clampingthrough a recess 102in bracket 85. v ribbon-guide roller secured to shaft 97 bar intoaction, but not sufliciently far tocause the looping-fingers to operate.I

It is desirable to provide positive means for feeding the ribbon fromits spool or beam as fast as is necessary to supply the length requiredin the trimming as it is made and in the loops as they are formed,thereby delivering the ribbon freelywithout subjecting it to tension. Tothis end the following mechanism is provided: 85 is a bracket (shownsepar-' ately in Fig. 5) secured to the beam-stand 4:6. This bracket isprovided with a T-slot 86, containing a nut 87, (see Fig. 6,) which fitstherein neatly, so as to be incapable of turning therein. 88 is a bolthaving a reduced end 89 adapted to engage the nut. Loose on the bolt 88is a ratchet-wheel 90, the hub of which is provided with a key 91. 92 isa gear-Wheel having akeyway. By means of this key and keyway-the gear 92is secured to the ratchetr wheel 90, so as to turn therewith. 93 is alever pivoted between its ends on bolt 88. By screwing up the bolt 88the nut is drawn to ward the outer wall of the slot 86, and the shoulderformed at the beginning of the reduced portion of bolt 88engages theouter face of the bracket 85, thereby securely fastening the ratchet 90,gear 92, and lever 93 in position. 94 9t are pawls pivoted to lever 93'on each side of the ratchet and adapted to turn the ratchet at eachreciprocation of lever 93.. -The lever 93 is operated by connecting oneend thereof with the lever 106 on the shaft 79 by means of the link 95.

96 is a shaft extending across the machine and turning in bearings inthe beam-stand.

The shaft 96 also extends through an orifice 101 in the bracket 85. is agear-Wheelsecured to shaft 96 and meshing with the gear 92. 97 is aribbon-guide roller secured to shaft 96. 98 is another shaft extendingacross'the machine and turning in bearings in the beam-stand. The shaft98 extends 99 is a 103- 103 are brackets secured to the beam-stand, and10 1 a shaft extending across the machine and supported in saidbrackets. 105 repre sents ribbon-spools arranged along said shaft.

-Each ribbon extends from its spool 105 to and partly around roller 99,thence between rollers 99 and 97, thence'partly around roller97,-and'thence down to the guides and needles. As a lug on thepattern-chain passes under and elevates the end of the bell-crankconfined between rollers 97 and 99 are thereby fed ofl their spools 105.It will be understood that the ribbon is fed from its spool or beam eachtime the bell-crank is under-ridden by a lug whether high or low. Whenthe mechanism is actuated by a low lug, the ratchet will be turned, say,only one tooth, Whereas when the mechanism is actuated by a high lug theratchet will be turned a plurality of teeth. Thus the ribbon will be fedfrom its spool or beam during the operation of the looping-fingers andalso during the normal knitting operation. The length of ribbon fed fromthe spools at each operation of the actuating mechanism may be regulatedin different ways. For example, gears of different sizes may besubstituted for the gears 92 and 100 to turn the latter a greater orless distance on its axis, and thus increase or decrease the feed, orthe link 95 may be adjusted at diflerent positions along the lever 93.
